Abstract

A new and distinct Rhipsalidopsis plant named ‘PKMRhips09’ particularly characterized by its compact plant habit; dense and bushy plant form; moderate growth rate; and orange-red colored buds and flowers.

Description

Latin name of the genus and species of the plant claimed: Rhipsalidopsis Britton et Rose.
Variety denomination: ‘PKMRhips09’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Rhipsalidopsis, botanically known as Rhipsalidopsis, sometimes referred to as Rhipsalidopsis Britton et Rose, including Epiphylopsis Berger, commonly known as either Easter Cactus or Spring Cactus, and hereinafter referred to by the cultivar name ‘PKMRhips09’.
The new Rhipsalidopsis cultivar is a product of a controlled breeding program conducted by the inventor, Christian Hald Madsen, in Søhus, Denmark.
The new Rhipsalidopsis cultivar originated from a cross made by the inventor in 2007 in Søhus, Denmark. The female and male parents are unpatented, proprietary Rhipsalidopsis×hybrida cultivars. The new Rhipsalidopsis cultivar was discovered and selected by the inventor as a single flowering plant within the progeny of the stated cross in a controlled environment in 2010 in Søhus, Denmark. The inventor selected ‘PKMRhips09’ on the basis of its flower color and compact, freely branching, upright growth habit.
Asexual reproduction of the new Rhipsalidopsis cultivar by phylloclade cuttings was first performed in 2008 in Søhus, Denmark, and has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction. The new cultivar reproduces true to type.
BRIEF DESCRIPTION OF THE INVENTION
The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PKMRhips09’ which distinguish this Rhipsalidopsis as a new and distinct cultivar:
    • 1. Upright growth habit and upright flowers;
    • 2. Moderately vigorous growth; and
    • 3. Orange-red colored buds and flowers.
Data and plants of the parent cultivars are no longer available for comparison with the claimed cultivar.
The most similar commercial cultivar to the instant cultivar ‘PKMRhips09’ is the Rhipsalidopsis cultivar ‘PKMrh02’ (Patented, U.S. Plant Pat. No. 21,425). Plants of the instant cultivar ‘PKMRhips09’ differ primarily from plants of Rhipsalidopsis ‘PKMrh02’ in the following characteristics:
    • 1. Plants of ‘PKMRhips09’ have shorter phylloclades than plants of ‘PKMrh02’ and are thus lower overall in total height;
    • 2. Plants of ‘PKMRhips09’ have more red colored flower buds and flowers than plants of ‘PKMrh02’;
    • 3. Plants of ‘PKMRhips09’ have white filaments whereas plants of ‘PKMrh02’ have purple filaments;
    • 4. Plants of ‘PKMRhips09’ do not have purple phylloclade margins while plants of ‘PKMrh02’ have purple phylloclade margins; and
    • 5. Plants of ‘PKMRhips09’ have less dark purple ovaries than plants of ‘PKMrh02’.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
The accompanying photographs illustrate the overall appearance of the new Rhipsalidopsis cultivar ‘PKMRhips09’ showing the colors as true as is reasonably possible with colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the color of ‘PKMRhips09’.
FIG. 1 shows a typical flowering plant of ‘PKMRhips09’ grown in a 10.5 cm pot.
FIG. 2 shows a close-up view of typical buds, flowers, and phylloclades of ‘PKMRhips09’.
FIG. 3 shows a typical lateral branch, with phylloclades, buds, and flowers of ‘PKMRhips09’.
FIG. 4 shows a comparison of a typical plant of ‘PKMRhips09’ (center) with a typical plant of a similar variety ‘PKMRhips08’ (left) and a typical plant of the comparison variety ‘PKMRh02’ (right).
FIG. 5 shows a comparison of typical laterals branches, with phylloclades, buds, and flowers, of the varieties ‘PKMRhips09’, ‘PKMRhips08’, and ‘PKMrh02’.
DETAILED BOTANICAL DESCRIPTION
The new Rhipsalidopsis cultivar ‘PKMRhips09’ has not been observed under all possible environmental conditions. The phenotype of the new cultivar may vary with variations in environment such as temperature, light intensity, and day length without any change in the genotype of the plant.
The aforementioned photographs, together with the following observations, measurements and values describe plants of ‘PKMRhips09’ as grown in a glass-covered greenhouse in Fyn, Denmark, under conditions which closely approximate those generally used in commercial practice, where day temperatures in the greenhouse average 18° C. and night temperatures in the greenhouse average 16° C. Ambient light levels used while growing plants of ‘PKMRhips09’ are +50 Wm2. No growth retardants were used when growing plants of ‘PKMRhips09’.
The age of the ‘PKMRhips09’ plants described is about 10-12 months after propagation and grown in 10.5 cm pots. The photographs and descriptions were taken during the winter season. Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.), 5th edition, except where general colors of ordinary significance are used.
